A camera connected in USB slot! Cool, what about to make a new Hombrew like the USB-loader, that could get data from a connected usb-camera and translate this data onto the wii! Just like Shape recognition (circle/square/triangle drawn on piece of paper, which is shown to the video camera! )

I'm sure We/Wii have hier (on this awsome big dev-site... ) very talented & skilled coders who would take & hit this very exciting challenge: making a USB-BodyMotion !
